Discontinuous games, such as auctions, may require special tie-breaking rules to guarantee equilibrium existence. The best results available ensure equilibrium existence only in mixed strategy with endogenously defined tie-breaking rules and communication of private information. We show that an...

Rubinstein and Wolinsky (1990b) consider a simple decentralized market in which agents either meet randomly or choose their partners volunatarily and bargain over the terms on which they are willing to trade. Intuition suggests that if there are no transaction costs, the outcome of this matching...

In an intertemporal general equilibrium framework, we compare a Cournot equilibrium to the Walras equilibrium. The Cournot agents trade and invest less than the Walras agents. This generates an ineffciency which does not vanish as the number of Cournot agents tends to infinity. A larger number...

We are developing a theory of equilibrium market instability in a general equilibrium duopoly caused merely by strategic trade. An economy is described as a strategic market game, where players have market power as buyers and sellers. First order conditions of individual decisions are first kind...

We consider a class of equilibrium refinements for finite games in strategic form. The refinements in this family are indexed from least to most restrictive. Proper equilibrium is obtained as a special case within the class; all other concepts are stronger than trembling-hand perfection and...

The repeated game literature studies long run/repeated interactions, aiming to understand how repetition may foster cooperation. Conditioning future behavior on past play is crucial in this endeavor. For most situations of interest a given player does not directly observe the actions chosen by...

We develop a theory of equilibrium market volatility in a general equilibrium duopoly with complete information. The resulting economic system possesses a property, which can be described as ‘natural volatility' of markets, even if players have complete information.Economy is described as a...

We are constructing an imperfect competition general equilibrium model, with non-consumable money and labor market; our toolkit is an equilibrium default model of Shubik-Wilson (1978). Our result has an ‘equilibrium volatility' simultaneously occurring at all three markets: labor, goods, and...
